What Is Chrultrabook Docs and Who Is It For?

Updated

Chrultrabook Docs is a documentation site for people who want to replace ChromeOS on a Chromebook with another operating system. It covers how to swap the OS on your device and includes extra information to help you get the most out of it afterward. The site is explicit that this is not a one-click procedure: you are expected to have some technical background and troubleshooting skills before you start.

What the site covers

The documentation is organized around the goal of turning a Chromebook into an Ultrabook-style machine running a different OS. Based on the site's own description, its scope includes:

  • OS replacement instructions — information on how to replace ChromeOS on your device.
  • Post-install and extra information — material to help you get the most out of the device once the new OS is in place.

The homepage presents this as a single starting point ("Get Started") alongside a community forum for discussion, and invites readers to help improve the documentation on GitHub.

Who should use it

The site states its audience directly: people looking to replace ChromeOS with a different OS. That makes it a fit if you already know you want to move off ChromeOS and are looking for device-specific guidance.

It is a poor fit if you expect a guided, low-risk process. The documentation warns that the work is technical in nature and assumes existing troubleshooting ability. Before committing, honestly assess whether you can:

  • Follow multi-step technical instructions without hand-holding.
  • Diagnose and recover from problems when something does not work as described.
  • Accept that the process is not a single click or a simple toggle.

How to use it

  1. Confirm your goal matches the site's scope — replacing ChromeOS with another OS on a Chromebook.
  2. Start from the "Get Started" entry point on the homepage and follow the documentation for your device.
  3. Use the forum for discussion when you hit questions the docs do not answer.
  4. Check back on GitHub — the site notes that the documentation is improved collaboratively, so content may be updated over time.

The expected result is a Chromebook running a different operating system, with the documentation as your reference throughout. The main sticking point to plan for is technical difficulty: the site does not present this as a beginner-friendly or automated process, so budget time for troubleshooting rather than assuming a smooth first attempt.

A practical example

For instance, if you have an older Chromebook you no longer use with ChromeOS and want to run a lightweight Linux setup on it, this documentation is aimed at exactly that task. You would begin at "Get Started," work through the OS replacement information for your device, and keep the forum open for issues along the way — while expecting to solve problems yourself rather than following a one-click installer.
